Phenolic CE C-COARSE
Properties of the C-COARSE condition, compared with the other Phenolic CE grades.
Choose the coarse-weave C grade for thick, heavily loaded mechanical parts where maximum impact strength matters more than machined surface finish.
What is Phenolic CE C-COARSE?
Phenolic CE C-COARSE is Phenolic CE in the C-COARSE grade — choose the coarse-weave C grade for thick, heavily loaded mechanical parts where maximum impact strength matters more than machined surface finish. Phenolic CE C-COARSE has a tensile strength of 70 MPa (10.2 ksi), weaker than 85% of composite grades. Elongation at break is 1.5% and the elastic modulus is 7 GPa (1.02 Msi). Phenolic CE C-COARSE has a density of 1.37 g/cm³ (0.0495 lb/in³), lighter than 68% of composite grades. Its glass-transition temperature is 160°C (320 °F). Phenolic Matrix is the default condition FabDigit quotes; C-COARSE is available on request or by drawing note.

Working with Phenolic CE C-COARSE
Is Phenolic CE easy to machine?
Machines and taps cleanly with carbide or PCD tools at high speed and low feed; dust is abrasive and irritant, so use extraction and expect tool wear rather than gumming.
Can Phenolic CE be welded?
Thermoset laminate cannot be welded or heat-formed; join by bolting, riveting or epoxy adhesive bonding after abrading the surface.
Can Phenolic CE be formed, bent or molded?
Supplied only as press-cured sheet, rod and tube; thin sheet (<1.6 mm) can be punched warm (~90–120 °C), thicker stock must be machined to shape.
What surface finishes work on Phenolic CE?
Sand and seal cut edges (varnish/epoxy) to limit moisture pickup; can be painted after abrasion, but not platable and only moderately polishable due to fabric texture.
Phenolic CE chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| phenol-formaldehyde resinresole/novolac phenolic binder, fully cured | 35 – 48 | 42 |
| cotton fabric (fine weave)plain-weave cotton cloth, ~4 oz/yd² class for CE | ≥ 52 (balance) | — |
Phenolic CE C-COARSE — frequently asked
What is Phenolic CE C-COARSE used for?
Phenolic CE C-COARSE is typically used for precision gears and pinions, bushings and plain bearings, electrical insulators and terminal boards, wear pads and guide strips, cam followers and timing gears and machine tool slides and soft jaws. In short: cotton phenolic gear stock.
What is the tensile strength of Phenolic CE C-COARSE?
Phenolic CE C-COARSE has a typical tensile strength of 70 MPa (10.2 ksi) — weaker than 85% of composite grades. Strength varies by condition: see the 3 listed tempers.
Is Phenolic CE C-COARSE easy to machine?
Yes — machinability is rated very good (72/100, better than 79% of composite grades). Machines and taps cleanly with carbide or PCD tools at high speed and low feed; dust is abrasive and irritant, so use extraction and expect tool wear rather than gumming.
Can Phenolic CE C-COARSE be welded?
